Function[xx,Through[{f[#[[1]]]&,g[#[[2]]] &}[xx]]]/@{{x1,y1},{x2,y2},{x3,y3}} could do the trick.

Another simple question - though I guess this will require more complex syntax. Suppose I have the list, data = {{x1,y1},{x2,y2},{x3,y3}} and I want to produce the result (for fitting/plotting) data2 = {{f[x1],g[y1]},{f[x2],g[y2]},{f[x3],g[y3]}} I assume that if there was only one transform I wanted to apply, f[x], then I could say data2 = f[data] but how about this more complicated transform with functions f and g? again thanks! Your replies have been very helpful! Nathan Moore, University of Minnesota Physics
